What is IPFS?
IPFS stands for Interplanetary File System, a peer-to-peer distributed file system that connects all computing devices. More specifically, it will distribute stored data in the form of P2P, aka a peer-to-peer network.
In particular, IPFS’s activities mainly rely on the ability to calculate the bandwidth of all participating machines, not on a small part of central servers like the HTTP protocol.
In other words, IPFS is a completely decentralized content delivery network that allows flexible data storage and management. Each computer participating in the network assumes the task of downloading and uploading data without the intervention of a central server.
How IPFS does works?
First, all data is encrypted and stored as a hash (also known as an IPFS object). The main idea is that if your browser wants to access a certain page on IPFS, just give it a hash and the network will find the machine that stores the data that matches the hash and then download the data, the page. from that computer to you.
The way IPFS works will be similar to BitTorrent, meaning that each computer participating in its network will take care of both downloading and uploading data without the presence of a central server. In general, the way IPFS works will have 2 main parts:
- Identify the file with the content address (the hash value of that file).
- Find stored data and download: when you have the hash of the file or page to download, the network will find and connect to the best machine to download the data for you.
Unique feature of IPFS
If implemented correctly, IPFS offers great potential by improving data transfer rates, avoiding reliance on servers, and saving costs.
Avoid server dependency
In Client-server models like HTTP, when servers are experiencing problems, they will not be able to respond to users. This is also the biggest problem that the HTTP protocol has when it depends on a centralized server, which it cannot improve or fix.
With IPFS, it completely ignores the concept of a server, and only cares about the content of the search. This not only helps us shorten the path to information but also does not worry about encountering low-quality, unreliable servers.
Decentralized model
With a centralized model, large amounts of data are concentrated in the hands of some big names in the field such as Facebook, Amazon, Google, etc. This inadvertently makes them the focus for hackers to attack. . In history, many times we have witnessed information leaks related to big names.
With the decentralized website model of IPFS, these problems are completely overcome and there is no longer a decentralized management model. The data is stored distributed and without a centralized server to attack, the more people participate in IPFS, the more secure the network will be and harder to manipulate.
Reduce costs
The next advantage of the IPFS model is that it reduces costs for both content providers and ordinary users. IFPS will allow the above video to be completely downloaded to the IFPS intranet no matter who you are and where you are.
Thus eliminating the need for a series of docking stations and Internet servers, resulting in a marked reduction in overall costs.
Potential applications of IPFS in Blockchain
The core technology of IPFS is based on a distributed hash table (Distributed Table Hash) on a decentralized peer-to-peer network (P2P Network), Blockchain uses distributed ledger technology, because of the same structure, the two platforms These technologies can be combined with each other.
With the advantages of high security, better data transmission thanks to a decentralized operating model, IPFS promises to become an indispensable component in Web 3.0 infrastructure, allowing storage Preventive decentralized data storage against manipulation and tampering.
Besides, IPFS will also become the preferred storage platform of many Dapps because of its censorship resistance.
